Description

Technical Field

[0001] The utility model relates to the technical field of air preheater cleaning equipment, in particular to a cleaning device for heat storage elements of air preheaters in power plants. Background Art

[0002] After the coal blending and denitrification systems were commissioned, ammonia escape led to the formation of ammonium bisulfate, which condensed on the surface of the air preheater's heat storage elements. This caused severe dust accumulation inside the air preheater and increased the air preheater's differential pressure. To reduce the differential pressure, continuous soot blowing and high-pressure water flushing of the heat storage elements were implemented. This resulted in enamel peeling, element deformation, and corrosion of the base material, resulting in reduced heat exchange efficiency, fluctuating boiler furnace pressure, and increased induced draft fan current, posing a safety hazard to the unit's stable operation.

[0003] The air preheater and the internal heat storage elements need to be cleaned regularly. Generally, the cleaning operation is done manually, which is prone to accidental burns. There are also dead corners that are difficult to clean, making the overall operation time-consuming and labor-intensive, affecting normal needs. Cleaning equipment also needs to be switched at any time, increasing the labor intensity of manually moving each device.

[0004] Therefore, the utility model provides a device for cleaning heat storage elements of air preheaters in power plants. Utility Model Content
